This bill makes several amendments to the General Laws related to Municipal Employees' Arbitration. The amendments clarify the rights of municipal employees to organize and bargain collectively, and establish a method of arbitration for settling disputes between employees and employers. The bill also specifies factors to be considered by the arbitration board and provides for the review of arbitration decisions by the supreme court.

One of the key changes in this bill is the establishment of new factors for the interest contract arbitration board to consider when making decisions on contracts. These factors include comparing wage rates, hourly requirements, and conditions of employment with prevailing rates in the local area, as well as considering the interest and welfare of the public. The bill also grants the board the power to make decisions on all negotiated matters, including the expenditure of money.
